These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Flowers in the Attic
Complete Monster: We have Corrinne and Olivia Foxworth. Olivia, Corrinne's mother, is a fanatic who tortures and abuses her family for what she perceives as "sinful." Corrinne, having lost her parents' favor by running away and marrying her own uncle, wants to inherit the family fortune, but cannot if she and her husband had children. She and Olivia lock Corrinne's children in the attic where they leave them for over a year and conspire to slowly poison them in order to do away with the children with none the wiser. The youngest child Cory dies from this.
Jerkass Woobie: Olivia the grandmother when her past is revealed in the prequel book Garden of Shadows.
